Editor's note: This story has been corrected to reflect that the Milligans have three children, ages eight, six and four.

Williamson County Commissioner Matt Milligan announced Monday he's resigning later this month.

First elected in August of 2014, Milligan, 39, and his family are moving out of District 3, in Spring Hill.

"I didn't want to have to do this, but I'm putting down something good to pick up something great for now," Milligan said Monday. "It's just a hard announcement."

Milligan and his wife both work at Lipscomb University and said the commute was over an hour one-way every day. With two children ages six and four, Milligan said he wanted to spend more time with his family.

He and his family are moving to the River Oaks subdivision in Brentwood, and the shorter commute to work means more time spent with his three children, ages eight, six and four.

"I'm thrilled to maximize my time with them right now," he said.

Milligan's fellow commissioner representing District 3, David Pair, will nominate an interim commissioner in September. Other commissioners may also make nominations, Milligan said. The full commission will then vote for a replacement.

"I chose to time this process for (July) because commission doesn't meet in August," Milligan explained. That will give Pair and the other commissioners an extra month to conduct a thorough search.

Milligan said it's been an honor to serve Spring Hill on county commission and said he may run again in the future.

"It's been a thrill," Milligan said.

"I've enjoyed representing Spring Hill, fighting for the schools, for teacher pay and the [education] impact fee," he said. "I've enjoyed good, robust debate, and getting to know these public leaders."

Those interested in representing Spring Hill on the commission can submit resumes and cover letters to County Commission until Aug. 28.
